Suddenly, he became a weak pitcher for left-handed hitters.

As a closer in the future, it may be a big burden.

Hanwha Eagles closer Kim Seo-hyun met KT Wiz and LG Twins last week and had a tough week. He took the mound in four games, recording one loss, one save, and one hold, and his ERA was 27.00 with one Blon save. He had nine hits and allowed eight runs in two ⅔ innings.




It was not Kim Seo-hyun, who previously allowed eight runs in 46 ⅓ innings.

Kim Seo-hyun, who took the mound in the top of the eighth inning of the KT match on the 5th and allowed Kang Baek-ho to have a come-from-behind three-run hit against the top of the right monster wall, managed to secure the victory on the 6th, but became a losing pitcher against LG on the 8th after a walk-off hit in the bottom of the 10th inning. After taking the mound in the bottom of the ninth inning with a 5-2 lead on the 10th, he allowed two runs on three consecutive hits after holding two outs, revealing his anxiety again. Austin Dean was caught on a foul fly to third baseman and managed to finish the game.

If you look closely at Kim Seo-hyun's performance last week, there is noticeable data. I was intensively hit by a left-handed batter.




Kim Seo-hyun is a three-quarter pitcher, so he seems weak to left-handed batters, but the previous data has been good at preventing left-handed batters and right-handed batters. His performance until August 4 was .203 (15 hits in 74 at-bats) for right-handed hitters and .207 (18 hits in 87 at-bats) for left-handed hitters. There was no difference.

However, KT and LG faced heavy fire from left-handed batters last week. At KT, I happened to meet Kang Baek-ho twice and all of them had hits. He struggled even more against LG, which had many left-handed batters. In the bottom of the 10th inning of overtime on the 8th, Kim Hyun-soo and Oh Ji-hwan doubled, and eventually allowed Chun Sung-ho to have a walk-off hit, becoming a losing pitcher. All of them have left-handed hitters. Park Hae-min, Shin Min-jae, and Moon Sung-joo also had hits in succession in Tuesday's game. Chun Sung-ho, who came out as the first batter, also had a hit, but second baseman Lee Do-yoon's good defense caught him out. He was hit hard by left-handed hitters.

Last week, he had a hit rate of .25 with one hit in four at-bats for a right-handed batter, but he had a hit rate of .667 with eight hits in 12 at-bats for a left-handed batter. So the hit rate for left and right hitters changed throughout the season. The hit rate for right-handed hitters this season was .256 (16 hits in 78 at-bats), but the hit rate for left-handed hitters soared to .263 (26 hits in 99 at-bats).




He became a weak pitcher for a left-handed batter in a week.

We can watch the next game to see if it is a brief slump or a weakness that will continue. Hanwha meets Lotte Giants and NC Dinos this week. Lotte has left-handed hitters such as Reyes and Jang Doo-sung, Hwang Sung-bin, Ko Seung-min, and Noh Jin-hyuk, while NC has left-handed hitters such as Park Min-woo, Kim Joo-won, Choi Won-joon, Hong Jong-pyo, and Choi Jung-won.

Kim Seo-hyun should quickly get out of being hit by a left-handed batter. If the perception that the left-handed batter is weak is embedded, the pitcher's self-confidence may decrease. Kim Seo-hyun, who has made 25 saves to put Hanwha in the first place competition so far, will suffer from growth pain at the end of the season.
